👉 The term "overbore" is a mathematical concept that refers to a function or curve whose derivative is not equal to zero. In other words, it has an infinite number of points where its derivative is undefined. For example, consider the function f(x) = x^2 - 4x + 3. This function has an overbore at x = 1 because the derivative (f'(1)) does not exist at that point due to the nature of derivatives and their behavior
